I have a 2011 suburban with a radio that is going crazy. Sometimes it will just starts switching back and forth out of auxiliary input and fm. It seems to do it more in the summer. Sometimes it won't do it at all. It does it when nothing is plugged in to either the aux or USB . I'm out of warranty . Please help

 

Is this a touchscreen model? If so, I would try cleaning the screen with a lint free soft cloth and some water, paying close attention to the corners of the screen. I would also remove the nav disc (I think all touchscreens are nav) and try cleaning and reinserting that disc as well.

When I first got my truck (used) the touchscreen wouldn't respond to presses properly or lagged the response and sometimes even just locked up. I did the above and the problems went away. I think the problems had more to do with the dirty disc than anything else, but at least I can use it now.

Not sure if the 2011's radio is the same as the 2007, but the advice is free.

It is not a navi unit. Just a regular unit with cd/aux/usb and Bose speakers

 

Well I want to say loose connections, however I don't think a loose connector would cause what your describing. Sounds more like a worn or sticky button. Has anything every been spilt on the unit, like coffee or soda?

If its internal to the radio its probably better to replace the unit completely than trying to fix yourself, unless your versed in such things..
